Studies of Rain Erosion Mechanisms in a Range of I.R. Transmitting Ceramics Including Coated Samples.

摘要

The report starts by summarising the techniques and approaches used in this laboratory to study liquid impact, rain erosion damage mechanisms and the strength properties of window materials. Recent progress is then discussed. This includes (i) a recalibration, and extension to lower velocities of the 'equivalent drop size' data for the impact of jets from the Cambridge single impact apparatus (ii) a summary of recent work on zinc sulphide, including the work on various coated systems.
